The output voltage of the TPS6213x devices can be increased by 5% above the nominal voltage by setting the DEF pin to High.⁽¹⁾ When DEF is Low, the device regulates to the nominal output voltage. Increasing the nominal voltage allows the user to adapt the power supply voltage to the variations of the application hardware. More detailed information on voltage margining using TPS6213x can be found in Voltage Margining Using the TPS62130 Application Report. A pulldown resistor of approximately 400 kΩ is internally connected to the pin to ensure a proper logic level if the pin is high impedance or floating after initially set to Low. The resistor is disconnected if the pin is set High.
